7 Installation Information FLUIDS - Most premium grade petroleum base fluids can be used with GC Motors. Optimum operating viscosity is cst ( SSU) at maximum rated speed. Minimum operating viscosity is 10 cst (59 SSU). Maximum operating viscosity is 750 cst (3409 SSU). Maximum cold start viscosity is 2000 cst (9091 SSU). Contact us for additional information regarding the GC performance using other fluids. OPERATING TEMPERATURES - Fluid temperature range (Mineral Oil): Max. 93ºC (200ºF) continuous and Max. 105ºC (221ºF) intermittent. FILTRATION - Proper filtration is critical to the trouble free operating of any hydraulic system. For optimum motor life at maximum pressure ISO 4406/1986 ( 18/14) is recommended. A 10-micron filter sized to accommodate full system return flow is recommended for most operating environments.

8 W SERIES HYDRAULIC MOTORS W Series motors are available in 3 families with displacements ranging from.183 in. 3 to 3.05 in. 3 (3 cc to 50 cc). W Series motors are available in both unirotational or birotational configurations. All feature a three-piece bushing block design for high pressure operation. A number of shaft and flange combinations are available. Integral valve options provide ease of system design. A key feature of all motors in the W Series is the extremely high volumetric efficiency.

21 Installation Information FLUIDS - Most premium grade petroleum base fluids can be used with WM900 Motors. Optimum operating viscosity is cst ( SSU) at maximum rated speed. Minimum operating viscosity is 10 cst (59 SSU). Maximum operating viscosity is 750 cst (3409 SSU). Maximum cold start viscosity is 2000 cst (9091 SSU). Contact Concentric for additional information regarding the W900 performance using other fluids. FILTRATION - Proper filtration is critical to the trouble free operation of any hydraulic system. For optimum motor life at maximum pressure ISO 4406/1986 ( 18/14) is recommended. A 10-micron filter sized to accommodate full system return flow is recommended for most operating environments. PERFORMANCE DATA - The motors will rotate also at differential pressure p<25 bar according to actual conditions. However, for specified motor performance data a continuous differential pressure of p>25 bar is required from inlet to outlet. Motors specified for only one direction with internal drain cannot be loaded at their outlet port by back pressures which exceed shaft seal capabilities (see page 20). If these pressure limits cannot be met, you must use bi-directional motors with external drain. For the external drain port, the above mentioned back-pressure limits are still valid. It is recommended that case drain lead directly to the oil reservoir. Do not connect it to the return line with filters or manifolds because of possible back-pressure peaks. The bi-directional ( ) motors have an external drain port as standard, the above mentioned back-pressure limits are also valid for these motors. TESTING - Product has been tested to 1,000,000 cycles at p I. Intermittent pressure p II is permitted at max. 20 sec loaded following 10 sec minimum unloaded. Product has been tested to 500,000 cycles at p III. Above represents performance, which can be expected from units incorporating flange port styles. Threaded side ports can affect the fatigue lifetime of motor housings. Do not use fittings with metal sealing edge. Do not overtorque the fitting. CAUTION - The peak pressure and rated pressure are for motors incorporating flanged port styles only. Whenever threaded ports are needed, a de-rated pressure has to be considered. Consult a Concentric representative to verify compliance with high pressure applications using threaded ports in pumps or motors.
